The problem is that Slack doesn’t publish a comprehensive list of all the best integrations out there. So, the team at expense management startup Birdly have created Slack Stack, the best directory of Slack integrations that I’ve found so far.

The curated lists at Slack Stack cover analytics, bots, communities, developer tools and more. Birdly’s own Slack-based service gets a few plugs in there, but that can be forgiven seeing as they went to the effort to build this directory.
